the thing with those is that they are only for about 2 weeks, forsure better than doing nothing though, and you could meet new ppl/make friends with ppl ur age while still in EY.
you could also work in a gan/kaytana- (summer camp version of a gan), work in a store/resturaunt, work in an american telemarketing office (there are a bunch of frum ones all over), be a house manager (cook/clean/watch kids for ppl- kinda like thurday chessed but get paid for it. not the funnest but if you find a really cute family you could get close to it might be worth it)
these are some things that don’t really require a degree or experience or anything like that.
